Comparison of Part and Full load Emissions of CI and HCCI Engine with Exhaust Gas Recirculation

Abstract

The present study is experimentation, not only on CI engine but also conducting experiment on CI engine running on HCCI mode operation without using exhaust gas recirculation and with using exhaust gas recirculation and comparing the emissions of both such as the Oxide of Nitrogen (NO_X), Oxides of carbon (CO), carbon dioxide (CO₂), Un-burnt hydro-carbons (HC)etc., These values are measured and compared under various conditions and plotted for easy understanding of effect of EGR on engine emissions. This paper focused on part load and full load emission comparisons for CI and HCCI mode operations with and without using exhaust gas recirculation. So separate experiments conducted and readings are recorded.
